Application filed March 10, 1916. Serial No. 83,316.

To all whom it may concern:

Be it known that I, WALTERJ. GILLER, a citizen of the United States, anda resident of VVarsaw, in the county of Hancock and State of Illinois,have ini'enteda new and Improved Evaporator, of which the following is afulLclear, and exact description.

My invention relates to an evaporator whereby liquids may be rapidlyevaporated, allowing the vapors therefrom to escape into 4 the open air,or to be condensed by any suitable means.

The object of the invention is to provide a simple, inexpensive andefiicient evaporator which is particularly adapted for the rapidconcentration of a solution; or the removal, by evaporation, of excesswater, or alcohol, or of both alcohol and water as in the case of beeror Wine.

With the above and other objects in View, the nature of which will morefully appear as the description proceeds, the invention consists in thenovel construction, combination and arrangement of parts as herein fullydescribed, illustrated and claimed. n the accompanying drawings, formingpart of the application, similar characters 0t reference indicatecorresponding parts in botl. views. s

Figure 1 is an elevation of the evaporator, the liquid container orkcttlebcing shown in. section, and part of the steam jacket about thedelivery conduit also being in section to show the details ofconstruction; and

Fig. 2 is a fragmentary elevation of a kettle partly in section to showthe spray nozzle in a different position.

Referring to the drawings, 3 is the container or kettle for boilingliquids. It has preferably a steam jacket 4 at the bottom for supplyingheat to the kettle to boil the liquid therein but any other suitablemeans maybe used. At the top the kettle has a flue or vent 5 forexhausting the vapors generated in the kettle. Rows of battle platesGare provided in the vent at the top of the kettle to prevent liquidparticles from being carried away by' the vapors. It will be noted thatthe rows of baiiies are disposed angularly to each other to form asinuous path or passage for the vapors passing from the kettle to thevent.

A. conduit extends from the bottom or the kettle to an inlet end of apump 8, the delivery conduit 9 of which pump leads to the top of andinto the kettle at a point above the highest possible liquid levelwithin the kettle. The conduit 9 within the kettle terminates with amultiple nozzle or nozzles 10 to break up the liquid into fineparticles. The conduit 5) is preferably surrounded with a live-steamjacket 11 to preheat the liquid circulating thcrcthrough to the boilingpoint.

The breaking up of a solution into line particles by the spray nozzlecauses a. slight reduction in temperature, which will cause acondensation of the parts of the solution which have a higher boilingpoint, thus the vapors of the lighter constituents of the solution willescape through the vent, while thc other vapors will be retained in thekettle.

The vent 5 may be connected to a vacuum pump so as to cause the boilingof the liquid in the kettle under a diminished pressure.

I claim:

1. An evaporator ot the class described comprisinga kettle tor boilingliquids, a pump, a conduit from the kettle,bottom to the pump inlet, aconduit from the pump outlet to the top of the kettle, a nozzle on saidconduit within the kettle for breaking up the liquid into a finelydivided spra v, means for carrying oil' the vapors from the kettle, andmeans for preheating the liquid in the conduit from the pump outlet tothe kettle.

2. An evaporator of the class described comprising a kettle for boilingliquids having a vapor exhaust at the top thereof, ballle plates in saidexhaust, a pump adapted to draw liquid from the kettle and discharge thesame into the kettle above the liquid level oi the kettle, means forbreaking up the discharged liquid within the kettle into a finelydivided spray, and means for preheating the liquid/o'n its dischargefrom the pump to the kettle.

3. An evaporator of the class described comprising a kettle for boilingliquids having a vapor exhaust at the top thereof, angularly disposedrows of battle plates in the exhaust at the kettle, a pump, a conduitfrom the bottom of the kettle to the inlet of the pump, a conduit fromthe outlet of In testimony whereof I have signed my\ the pump into thekettle at a point above name to this specification in the presence of nothe liquid 1level ofghe ksttl fa riiultigletwo subscribing Witnesses.sprai 'nozz e.on sai con m or rea ng 5 up t; 6 liquid into finelydivided sprays, and JOHN a state; in jacket on the conduit from the out-Witnesses: let dizthe pum' the kettle for preheating J.
